Slow Data Transfer on Slave Drive on a Dell Desktop System

Have you noticed a sluggishness in data transfer on your slave (secondary) drive that you add on a DELL desktop system? It runs extremely slow when copying/transferring files that it just boils you up to hell?

Here’s the solution:

The DELL BIOS does not actually enable DMA on the second IDE device on a given IDE channel by default (as DELL systems are configured to strict cable select).

You can just enter the BIOS (System Setup) by continually hitting F2 (that’s one of the function keys on keyboard) while the system is booting before it goes to the Windows Loading screen. In the BIOS, just change the setting on secondary master drive from “OFF” to “AUTO”.
